Student general numbers are concentrated in the general department, usually starting in August and ending in June of the following year, and are unlimited in non-special cases, making it easy to register. The biggest disadvantage of student visits: long time. The biggest advantage of student visits: patience and care. Quality assurance of student numbers: students are quality controlled by senior residents or attending physicians during their visits, and the treatment process will give necessary interventions depending on the patient’s condition and the student’s ability to strictly control the quality. The treatment cost of student numbers in the Department of General Dentistry, Peking University Stomatology Hospital, Huimin Chen: At present, except for patients of the medical insurance system (which requires online transmission of data to the medical insurance center and compliance with the regulations of the medical insurance center), the treatment cost of student numbers will be discounted to a certain extent. Currently, except for consumables, other costs can be calculated at a 20% discount in return for the patient’s support of the student’s educational efforts. Any senior specialist has grown up from a regular student, and we hope more patients will look to our student general numbers.
